Application iled J'uly 19, 1911.

To all whom t may concern.' i

Be it known that I, BRUCE FORD, a cit1- zen of the United States, residing at the city of Philadelphia in the count-yor` Philadelphia and State o Pennsylvania, have invented a certain new and useful Jar for Secondary or Storage Batteries, of which the following isa specification.

The principal object of the present invention is to avoid or prevent leakage between the several plate-compartments into which the jar is divided and at the same time to impart to the jar the necessary mechanical strength and rigidity without unduly increasing its weight.

To this and other ends hereinafter set forth the invention lcomprises the improvement to be claimed at the end hereof but to be first described in connection with the embodiment but not the only embodiment of it selected for illustration in the accompanying drawings in which- Figure 1, is -a top or plan view of a jar embodying features of the invention. Fig. 2, is a transverse sectional view taken on the line 2 2 of Fig. y1, and Fig. 3, is a sectional view taken on the line 3-3, of

Fig. 1, and showing only the lower portions of the jar.

The individual jars 1, 2 and 3, are arranged side by side in a `row with their abutting walls in Contact. These jars l, 2 and 3, are alike and a description of one will suiiice.

4, is the side wall and it may be lapped as usual on itself along the side of the jar and on the bottom wall 5, as indicated by the dot-ted lines in Fig. 1. The wall 4, may be comparatively thin and light even to an extent that would make it not self-supporting for reasons that will be present-ly described.

6, are plate holding ribs projecting up from the bottom 5, and 7, are supporting ribs projecting downward from the bottom 5. These ribs 7, may be faced with soft rubber 8.

9, is an outer side wall which surrounds and binds together the group or row of jars 1,2 and 3, and is lapped` on itself. The

outer side wall 9, is shown as extending arranged near the top and the bottom thereof. rlhe top hoop 10, may extend below the tops of the jars 1, 2 and 3. v

The described multi le plate-compartmen jar, when made Aof liard rubber, has its parts assembled in the manner described and upon vulcanization constitutes in eii'ect one piece.

Inasmuch as each of the jars l, 2 and 3, is complete in itself leakage from one jar to another is avoided even though the wall of one of the jars may be imperfect. j

The described arrangement by which all of the side or vertical walls are made double insures proper mechanical strength along with the hoops 10 and 11. The alined ribs G and 7, receive and support the Weight of the-plates of which a part of one A, is indicated by dotted lines in Fig. 3. The soft rubber cushions 8, tend .to absorb shocks when the jar is used for an ignition battery for an automobile which is its prin# cipal intended use.

WhatI claim is:

1. A multiple plate-compartment ar comprising a row of individual jars having their Side walls in contact, an outer side wall surrounding the row of individual jars and integral with their side Walls, and hoops encircling the outer wall and arranged near the top and bottom thereof, substantially as described.

2. A multiple plate-compartment jar comprising a row of individual jars having their side Walls in contact, and an outer side wall surrounding and integral with the row of jars and binding them together, substan' tially as described.

3. A multiple yplate-compartment jar comprising a row of individual jars having their side walls in contact and each having an internal plate rib and an external cushioned supporting rib alined therewith, an outer side wall surrounding and integral with the row of jars and binding them together, and hoops encircling and binding the outer side wall, substantially as described.

4. A multiple plate-compartment jar cornprising a row of individual jars having comparatively thin side Walls in Contact, an outer side Wall surrounding and integral with the ror of jars and reinforcing their 10 Walls and extending above the top thereof,
